PAINT-DIPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 755,349, dated March 22, 1904.

Application filed October 30, 1903. Serial No. 179,176. (No model.)

To all whom it may concern.-

useful Improvements in Paint-Dipping Ma chines, of which the following is a specification.

The object of my invention is to provide mechanism for automatically dipping articles into paint or other similar material in such manner as to evenly distribute the paint upon the article.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation in partial vertical section; Fig. 2, a section on line 3 3 of Fig. 1; Fig. 3, a section vertically through shaft 11 in Fig. 1,and Figs. 4: and 5 details of construction.

In the drawings, indicates a suitable frame in which is journaled a main drive-shaft 11, upon which are keyed two friction-disks 12 and 13, said disks being capable of axial movement upon the shaft. The disks 12 and 13 are connected by a suitable shifting-collar 14:, provided with suitable adjusting-screws 15, be-

tween which runsa cam-plate 16, carried by ashaft 17 parallel with shaft 11 and geared thereto by a suitable train of gears 18. J ournaled in frame 10 at right angles to shaft 11 is a shaft 19. Keyed upon the lower end of shaft 19 is a suitable friction-wheel 20, which lies between the two disks 12 and 13 and which may be adjusted radially with relation to said disks by any suitable means, such as a lever 21. Secured to the upper end of shaft 19 is a gear 22, which meshes with a gear 23. The gear 23 is supported between suitable parts 10 of the main frame 10 and is provided with a key 24:, which slides in a suitable keyway 25, formed in a vertical shaft 26, which extends through gear 23 and has its lower end mounted in a suitable step-bearing (shown in dotted lines in Fig. 1) and has its upper end passed through a suitable stufling-box .28 and into and through the paint-holding tank 29. The shaft 26 is provided below the arm 10 with a pair of collars 26, between which is arranged a finger or bar 30, which is prevented from rotating with shaft 26 by means of a depend-' ing rod 31, which passes through said bar.

The bar 30 is adapted to rest upon the periphery of cam 16 and as the cam rotates serves to raise and lower shaft 26, so that any article 32: secured to the upper end of shaft 26 may be lowered into the paint in the paint-tank and then raised out of thepaint. A suitable handlatch 30 is provided for engaging bar 30 and holding the same up when desired. Cam 16 carries a pair of cams 16 and 16", adapted to engage the adjustable fingers 15,and thus shift the disks 12 and 13.

The operation is as follows: The article 32 is placed upon the upper end'of shaft 26 and the parts then caused to rotate in the direction indicated by the arrows. As cam 16 is rotated beneath bar 30 said bar,together with the shaft 26 and the article 32, will be allowed to drop and the article 32 dipped into the paint and thereafter raised out of the paint. As soon as this occurs cam 16 comes into engagement with fingers 15 and shifts disk 13' into engagement with friction-wheel 20, thus rotating shaft 26 and causing the paint to flow outwardly toward the periphery of the article 32. The continued movement of the plate 16 brings cam 16 into engagement with fingers 15, and thus shifts disk 13 away fromengagement with wheel 20 and disk 12 into engagement with said wheel, thus suddenly reversing the direction of rotation of shaft 26 and causing the surplus paint on the article 32 to be thrown off and the remaining paint to be more evenly distributed. Cam 16 is then withdrawn from fingers l5 and the two disks 12 and 13 returned to normal position,-whereupon shaft 26 stops and the painted articles may be withdrawn .and' another substituted,

whereupon the operation isrepeated. Any desired speed may be obtained by shifting wheel 20 upon shaft 19.

I claim as my invention- 1. Ina paint-dipping machine, the combination, with a rotatable shaft adapted to receive the articles to be painted, of means for rotating said shaft, means for automatically ceive the articles to be painted, of means for rotating said shaft, means for automatically reversing the direction of rotation of the shaft, a receptacle for paint, means for bringing the article into and out of the paint, and means for varying the speed of the shaft.

3. In a paint-dipping machine, the combination, with a rotatable shaft to which the article may be secured, of a paint-tank through which said shaft extends, means for rotating said shaft in either direction, means for automatically raising and lowering said shaft through the tank, and means for automatically reversing the direction of rotation of said shaft.

4. In a paint-dipping machine, the combination, with a rotatable shaft to which the articles may be secured, of a paint-tank through which said shaft extends, means for rotating said shaft in either direction, means for automatically raising and lowering said shaft through the tank, means for automatically reversing the direction of rotation of said shaft, and means for Varying the speed of rotation of said shaft.

5. In a paint-dipping machine, the combination of a rotatable shaft to receive the articles to be painted, a paint-receptacle,driving disks 12 and 13, wheel 20 arranged between said disks to be engaged by either of said disks, driving connections between said wheel and the rotatable shaft, a cam drivingly connected with said disks, means operated by said cam for raising and lowering the rotatable shaft, and means operated by said cam for shifting the disks with relation to the wheel so as to change the direction of rotation thereof.

6. In a paint-dipping machine, the combination of a rotatable shaft to receive the articles to be painted, a paint-receptacle,drivingdisks 12 and 13, wheel 20 arranged between said disks to be engaged by either of said disks, driving connections between said wheels and the rotatable shaft, a cam drivingly connected with said disks, means operated by said cam for raising and lowering the rotatable shaft, means operated by said cam for shifting the disks with relation to the wheels so as to change the direction of rotation thereof, and means for radially adjusting said wheels with relation to the disk for changing the speed of rotation of the rotatable shaft.

7. In a paint-dipping machine, the combination, with a rotatable shaft to which the articles may be secured, of a paint-tank through which said shaft extends, means for rotating said shaft in either direction, means for automatically raising and lowering said shaft through the tank, means for automatically reversing the direction of rotation of said shaft, and means for holding the shaft up away from the automatic raising and lowering means.

8. In a paint-dipping machine, the combi nation, with a rotatable shaft to which the articles may be secured, of a paint-tank, means for rotating the shaft in either direction, means for automatically bringing the article into and out of the paint, and means for automatically reversing the direction of the shaft.

9. In a paint-dipping machine, the combination, with a rotatable shaft to which the articles may be secured, of a paint-tank, means for rotating said shaft, means for automatically bringing the article into and out of the paint, means for automatically reversing the direction of rotation of said shaft, and means for varying the speed of rotation of said shaft.

In witness whereof I have hereunto set my hand and seal at Indianapolis, Indiana, this 27th day of October, A. D. 1903.
